Unifying Parsing and Tree-Structured Models for Generating Sentence Semantic Representations (2022.naacl-srw)
Copied to clipboard
| Challenge: | Existing tree-based models require handannotated data to be trained. |
| Approach: | They propose a tree-based model that learns its composition function together with its structure. |
| Outcome: | The proposed model outperforms existing models on downstream tasks and is competitive with Bert base model. |
Syntactic Nuclei in Dependency Parsing – A Multilingual Exploration (2021.eacl-main)
Copied to clipboard
| Challenge: | Existing models for syntactic dependency parsing assume words are elementary units that enter into dependency relations. |
| Approach: | They propose to use composition functions to make a transition-based dependency parser aware of the notion of nucleus. |
| Outcome: | The proposed concept of nucleus gives small but significant improvements in parsing accuracy on 12 languages. |
